Food Net

FoodNet is a collaborative project of participating data collection sites in the CDC, US Department of Agriculture, and the US Food and Drug Administration (FDA) that became operational in 1995. It employs an active surveillance strategy for diarrheal illnesses and foodborne illnesses in sentinel populations monitored at over 300 clinical laboratories throughout the United States.24 FoodNet investigators actively contact these laboratories for confirmed cases of Salmonella, Shigella, Campylobacter, E. coli o157:H7, Listeria, Yersinia, Vibrio, Cyclospora, and Cryptosporidium. They have built a comprehensive database of foodborne illness in these regions.24 Physician practice patterns for ordering stool specimens have also been monitored. Population surveys create an approximation of the number of patients with diarrheal illness who seek medical care.24 This information is centrally based at the CDC and facilitates timely recognition and response to foodborne outbreaks.

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
